Getting back to a grid position.
The current position is not necessarily on a grid specified by the parameter QR when the power
is turned on or the Motor stops in an exceptional occasion because of an alarm or a warning.
In such a case, you may position the Motor to the nearest grid by an execution of incremental
user scale positioning.
For example in the figure below, the current position is in the range of grid 1, but not on the grid
1.
◊ Command IQ1
If the command IQ1 is executed at this moment, the Motor moves to the grid 2. That is,
the Motor moves to the first grid from the current position.
◊ Execute the command IQ0 to move the Motor to the original grid position, which is the
base point of the current position. That is, the Motor moves to the grid 1.
